Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

RXCGames.setLpPair(address,bool) (#432-444) compares to a boolean constant:
-enabled == false (#433)

Variable 'RXCGames._finalizeTransfer(address,address,uint256,bool).check (#661)' in RXCGames._finalizeTransfer(address,address,uint256,bool) (#651-678) potentially used before declaration: checked = check (#662)
